Application filed December 2, 1920. Serial No. 427,856.

To all 'whom t may concern.'

Be it known that I, FLErrcI-TERB. BURRIs, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Snowplows, of which the following `is a specification.

Another important object'of the invention y is to provide a snow plow of comparatively simple and efficient constructionembodying a scoop for gathering the snow and conveying means for carrying the snow from the scoop to a suitable place for discharging the same. f

Another object of the invention is to provide a device of the above nature including an inclined conveyor casing having an opening in the under side of the upper end thereof to effect ready discharge of the snow from the conveyor casing after it has reached the upper end thereof, without the use of means other than the conveyor for causing the discharge of the snow.

A still further object of the invention is to provide a particularly constructed scoop comprising an open ended casing whereby snow piling upon the scoop will be prevented 'from passing over the top of the same so as not to be gathered and `carried off/by the means provided for accomplishing this purose.

p Other objects and advantages of the invention will become apparent during the course of the followingdescription.

In the accompanying drawings,` forming a part of the application, and wherein like numerals are employed to designate like parts throughout the several views,

Figure 1 is a front elevation of the invention.

Figure 2 is a top plan thereof, with parts broken away.

Figure 3 is a transverse section taken on the line 3 3 of Figure 2, and

Figure 4 is a longitudinal section taken on the line 4-4 of Figure 3.

vthe drawings.

Referring to the drawings wherein for the purpose of illustration is shown thev preferred embodiment ofthe invention, the numeral 5 designates a scoop whichconsists of a casing of frustro pyramidal shape arranged upon its side as clearly shown in Both ends, or more accurately speaking, the top and bottom of the casing are open, the innerend of the casing being connected to a tubular conveyor casing 6 by a tubular portion 7, Aside of the conveyor casing 6 adjacent its lower end is provided with an opening 8 to receive material gathered -by the scoop so that the material may be delivered into the tubular conveyor casing.

The inner end of the scoop casing 5 which is connected to the portion Tis restricted, as is most clearly seen in Figure 3. rIhe scoop casing flares outwardly from the portion 'l' whereby the outer end edge 9 yof one side of the casing may be engaged with the ground for scooping the snow therefrom. In the lpresent instance, the scoop casing 5 is rectangular in cross section as clearly shown in Figure 1, but I desire to state that I do not limit myself to ythe number of sides which the scoop kcasing embodies. As the scoop casingfcontains two sides 10, a bottom or slide 11 and a top 12, it will be apparent that snow which is scooped up by the slide 11, will be prevented from passing over` the scoop by the provision of its top or roof 12.

Consequently, all snow engaged by the slide,

11 will be properly conveyed through the opening S into the lower end of the conveyor As best seen in Figures 1 and 2, the conveyor casing 6 is inclined upwardly of the i ,shaft of then auger extends longitudinally of the conveyor casing, through the same, both ends of the shaft being extended beyond the ends 13 of the conveyor whereby one end may be provided with a beveled gear 16 adapted for mesh with a similar gear 17 keyed to a power shaft which may derive its Al UU lio power from any suitable source. Acollar 18 is secured to the shaft within the conveyor casing to abut with the lower end thereof to revent downward sliding movement of the shaft relative to the conveyor casing due to the latters incline. The upper end of the shaft is threaded and extended beyond the upper end of the conveyor, and a nut or other suitable means 19 is positioned upon he extended end to abut the `outer surface of the upper end of the conveyor casing 6 to co-operate with the collar 1S in preventing improper movement of the shaft.

ln order that the snow or other material collected'by the device may be readily discharged from the upper end of the conveyor casing by the movement of the conveyor, an opening is provided in the relative under face of the casing adjacent the upper end, and is established by cutting away the major portion of `the circumference as clearly seen in Figures 2 and 3. This cutting away of the upper end of the casing permits. the

ortion 21 of the casing to properly support the end 13 thereof, whereby the shaft 14 may be journaled therein. By referring to the Figures 1 and 3, Ithe manner of attachment of the device to a vehicle, cart or suitable conveyance will be obvious in rthe light of the followinv explanation. The conveyor casing 6 may be supported in any suitable manner upon a conveyance ust so its lower y end is spaced from the ground and the casing inclined upwardly and outwardly of one sideof the conveyance so that the upper end of the conveyor casing will be disposed beyond the side of the conveyance for discharging the material collected. The casing is also so arranged with respect to the conveyance that the outer larger end of the scoop casing 5 is disposed forwardly o-f the conveyance and in a manner whereby the outer edge 9 of the bottom or slide 11 is en gaged with the ground or is arranged in slightly spaced relation thereto if found desirable.

When the invention is used the large end of Jthe scoop casing is disposed forwardmost, and it will be obvious that snow upon the ground will be scooped up by the slide and deposited within the lower end of the conveyor casing 6. Here, the snow or other material is engaged by the helical rib 15 of the auger and is moved upwardly toward the upper end of the conveyor casing. When the snow or other collected material reaches the opening 2O movement of the conveyor or helical rib willexert a force against the material and will cause the same to be effectively discharged through the opening to drop into a conveyance traveling alongside of the plough, or upon the ground to one side of the path being made by the device. It is intended that the conveyor may 'be rotated at a high speed in order that the snow collected by the vscoop may 'be readily carried off in case of a heavy snowfall.

The foregoing description and accompanying drawings have reference towhat might be considered 'to be the preferred or approved form of m invention. l desire it to be understood t iat l may make such changes inthe construction, combination and arrangement of the parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A snow co-llector comprising a stationary tubular casing having` its ends closed and adapted to be positioned in inclined relation on a vehicle with its upperv end disposed beyond one side of the vehicle and its lower end in proximity tothe ground, a rotatable screw or auger conveyor extending longitudinally through the casing and being `iournaled in the ends thereof, the relative underv surface of the upper end of said tubular casing having a discharge opening, the relative side of the lower end of said tubular casing' being provided with an opening, and a scoop extending vlate-rally of the casing and having a top, bottom and sides, said scoop communicating with said opening in the lower endV of the tubular casing whereby the material collected by the scoopis delivered laterally of' the auger and into the path-thereof through the opening in the lower end of the tubular casing.

In testimon whereof I affix my signature in presence o two witnesses.
